Description
This combined needle roller and cylindrical roller bearing carries radial load through the needle roller section and axial load in a single direction through the cylindrical roller bearing component, built to DIN 5429 with an end cap. Bore diameter is 45.0 mm, outside diameter 58.0 mm, height 32.0 mm, net mass 259.89 g. Limiting speed is rated at 5000 1/min, with a reference speed of 1900 1/min. The Z shielding on both sides protects the raceways from contamination while retaining grease inside the bearing, matching its design for grease lubrication rather than oil. Since the unit combines radial and single-direction axial support in one compact envelope, it suits mounting positions where both load types act on the same shaft location without needing a separate thrust bearing. The end cap allows direct shaft-end mounting, simplifying axial fixation of the assembly.
